SAFETY APPLIANCE FOR ELEVATORS.

Specification of Letters Patent.

Patented Aug. 26, 19219.

Application filed November 20, 1918. Serial No. 263,408.

To all whom t may concern:

Be it known that I, EDWARD TURGEON, a citizen of the United States of America, and a resident of Thompsonville, in the countyof Hartford and State of Connecticut, have invented a new and useful Safety Appliance for Elevators, of which the following is a specification.

My invention relates to improvements in safety appliance for elevators, and consists essentially of yielding, landing and elevator guards, landing trip mechanism and elevator trip mechanism with which said guards are respectively connected, oscillatory means operated by the elevator in ascending and descending, when angl accordingly as said firstnamed or said second-named mechanism is released, to throw ofi or disconnect the power from said elevator, and setting and resetting means, all of peculiar construction, together with such subsidiary and auxiliary parts and members as may be required or desired in order to render the appliance complete in every respect, all as hereinafter set forth.

The primary object of my invention is to provide means automatically to cut off the power from an elevator, whether the latter be ascending or descending, whenever an animate or inanimate obstacle or obstruction is thrust beyond the elevator floor into the elevator well when the elevator is ascending, on the one hand, or beyond the landing or floor into the path of the descending elevator, or is in the bottom of said well and so in such path, on the other hand.

A further object is to provide such means which is applicable to practically any type of elevator, power, and power-controlling mechanism. 4My appliance is adaptable to elevators of any size and regardless of the location and number of entrances thereto; to engineand electric-motor-driven and hydraulic elevators; and to ropeor cablecontrolled and electric-controlled elevators.

Still another object is to produce an appliance of this character which prevents the elevator from being started without setting the trip mechanisms, and from being restarted, when stopped by an obstruction, until such obstruction is removed, inasmuch aS the trip mechanism operated by said obstruction to stop the elevator can not otherwise be reset. An additional and valuable element of safety is thus introduced into the appliance.

A further object is to afford protection to the obstruction from the appliance itself.

A still further object is to prevent damage to the appliance in the event the elevator continues to travel beyond a certain distance, in either direction, after the operation of the trip mechanism involved takes place.

Other objects and advantages will appear in the course of the following description.

A preferred embodiment of the invention, whereby I attain the objects and secure the advantages of the same, is illustrated in the accompanying drawings, and I will proceed to describe said invention with reference to said drawings, although it is to be understood that the form, construction, arrangement, etc., of the parts and members in various aspects are not material and may be varied and modified without departure from the spirit of the invention.

In the drawings, in which like reference characters designate like parts throughout the several views, Figure l is a front elevation of an elevator well and elevator, showing a practical embodiment of my safety appliance as aforesaid, the same 'beingwithin said Well and applied to said elevator, and a landing or floor appearing in section; Fig. 2, an operation detail of the neutralizer cable for the starting and stopping cable of the elevator, with associated parts and members; Fig. 3, another operation detail of said neutralizer cable with said associated parts and members; Fig. fl, an inside elevation of a portion of the left-hand side or wall of the well, and of the .members on that side, a fragment of said floor appearing in section; Fig. 5, a similar view looking toward the right-hand wall of said well; Fig. 6, an operation detail of the rockers and their connections, shown in the preceding view, intermediate portions of the wall and of such connections being broken out; Fig. 7, a bottom plan of the neutralizer and other members at the top of the well; Fig. 8, a 'bottom plan of the elevator and attached parts; F 9, an elevation of the right-hand side of said elevator and attached parts; Fig. 10, a fragmentary section through the elevator floor or platform, taken on lines l0-10, looking in the direction of the associated arrow, in Fig. l; Fig. 1l, another fragmentary section through said platform. on lines 1.1-11, looking in the direction of the associated arrow, in Fig. 10; Fig. l2,

In illustrating the application of my invention, l have deemed it necessary to show merely rightand left-hand, side walls 1 and 2, `respectively, a rear wall 46, and a top 3, of an elevator well, without any of the customary inclosing members, including gates or doors, at the front, a single landing or floor 4 in front of such well, and a very simple form of elevator. It is to be understood, however, that, in practice, exposed and unprotected spaces atl the sides of the well in front will be closed, there may [be any number of floors or landings, and the elevator maybe as elaborate in structure and furnishings as desired. I have, furthermore, shown the elevator raised to an unusual height in the first view, but this is done in order to expose more of the appliance in said view, and a clear understanding of the operation is not thereby interfered with.

Y lt is assumed, in this case, that the source of the motive power for the elevator and device, apparatus,

the means of control for said powery are above the top 3.

Although the 'entrance-to' and exit from the elevator,V in the present example, are presumed to be at the front and there only,

`the appliance is equally well adapted for and adaptable to an elevator which opens on any other one side, or on any two or even more sides, itonly being necessary to arrange, locate, or extend the yielding guards accordingly.

lThe walls 1 and 2 are provided inside with vertical elevator guides 5-5.

The elevator, which is designed to travel Y up and down between the guides 5,"consists of a fioor or platform 6, and two uprights 7 at the sides, which uprights are connected by a cross bar 8. Braces appear Yat 9-9. The uprights 7 extend above and below theV platform- 6, and are provided with four, short channel-irons 11a, two on each upright, to engage the guides 5 and hold the elevator in place as it moves up and down.

In the center of the top of the cross bar or beam 8 is an eye-bolt 13, and a power chain or cable 14 is attached at one end to the same. The cable 14 passes over a sheave 1 6, under a sheave 17, and up through the top 4 to the winding mechanism which is not shown. rlhe sheaves 16 and 17 are mounted on two spindles 18 which are ournaled in two pairs of brackets 19, the latter being secured to the underside of the top 4.

Two vertical reaches, front and back, of a power-controlling rope or cable, are represented at 20 and 22, respectively. This cable is in front of the left-hand guide 5, and passes under a sheave 23 which is located near the bottom of the elevator well. The sheave 23 is mounted on a stud 24 that pnO- jects inwardly from a bracket 25 which is secured to the inner face of the wall 2. The reaches 20 and V22 of the aforesaid cable extend upwardly from the sheave 23,'past the elevator and within convenient reach of an operator on the platform 6, to the top 3, and through said top to the power-controlling or mechanism, which does not appear k1n connection herewith. For the purposes of this description, it is to be understood that, when the reach 22 is pulled down or the reach 20 pulled up, from neutral position, the elevator is caused to ascend, and, when said reach 20 is pulled down or said reach 22 pulled up, from suchl osition, said elevator is caused to descend, while the returning of the reaches to neutral position causes the elevator to stop in either case.

An equalizer or neutralizer, for the reaches 20 and 22, comprises a cord or cable 26, which has one end attached to a pin 27, Fig. 5, set in the wall 1 inside ofthe well and near the top 3, and at the other end has a branch 28 that extends and is attached to said reach 20 and a branch 29 that extends and is attached to said reach 22. A rocker 30, presently to be described, is pivoted at 31 to the wall 1 just below the top 3, and carries a vertical sheave 32. A bracket 33 is secured to the top 3, underneath the latter, and has a stud 34 upon which a horizontal sheave 35 is mounted, such sheave being back of and a little higher than the sheave 32. 'A- bracket arm 36 is pivotally supported at 37 from the top 3-see F ig. 7. At the right.- hand end of said armis a stud 38 upon which a horizontal sheave `39 is mounted. Means is provided to impart a movement or a tendency to a movement to the arm 36 that will carry rearwardly the end of the arm 36 which supports the sheave 39, and yielding to retain said arm in contact with a stop 40, which depends from the top 3 in front of a portion of the arm which is at the left of the pivot 37, such as a spring,` 41 having` its rear end attached to the left-hand end of said arm and its forward end to a pin 42 projecting inwardly from the wall For the sake of clearness the tension arm 36 and the spring 41 are omitted from Fig'. 1. A bracket 43 is secured to the inside face of the wall 2 about on a level with the sheave 32 across the well, and 'such bracket has a stud 44 upon which a vertical sheave is mounted.

The neutralizer cable 26 passes forward from the pin 27 to the sheave 32, up in front ofsaid sheave and rearwardly to the sheave 35, partially around the latter and obliquely to the sheave 39, which latter is located by the arm 36 approximately midway between the walls 1 and 2 and near the back side (46) 0f the well, obliquely to the sheave 45, and over the top of said last-named sheave. With this end of the cable 26 the upper ends of the cable branches 28 and 29 are connected, while the lower ends of said branches are connected with or attached to the cable reaches 2O and 22, in the manner previously explained. In Fig. 4 the neutral positions, as when the elevator is stationary or the shift is made to stop it, ,of the cable reaches 20 and 22 and the branches 28 and 29 are represented; in Fig'. 2 the positions which such members assume, when the shift is made to cause said elevator to ascend and while it is'ascending, are represented; and in 3 the positions of said members, when the shift is made to cause said elevator to descend and while it is descending, are represented. There is sufficient slack in the cable 26, when the reaches 20 and 22 and the branches 28 and 29 are in neutral position, and the rocker 30 with its sheave 32 is in initial position, with the axis .of said sheave in approximately the same vertical plane with the axis of the pivot 31, as shown in Figs. 4 and 5, to enable the shifts, which are represented in Figs. 2 and 3, to be made.

Each of such shifts takes the aforesaid slack out of the cable 26. It follows, therefore, that, if the rocker 30 be actuated on its pivot 31 to carry the sheave 32 forward, said sheave, in its forward movement, lengthens the reach of the cable 26 which is between the pin 27 and said sheave, by shortening,r that portion of said cable which extends from said sheave around the sheaves 35 and 39 and over the sheave 45 to the branches 28 and 29, and, in shortening said secondnamed portion of said cable, draws up Whichever of said branches is attached to the reach 20 or 22 that is in downward shift, and with it such reach, until both of said branches are positioned with their lower ends even with each other. Thus the reaches 20 and 22 are shifted to neutral position and the elevator is stopped.

The tension arm 36 does not ali'cct the 'cable 26 under ordinary conditions or cir cumstances, since the spring 41 is suliiciently strong to enable the neutralizer to perform its various functions without swinging said arm out of contact with the stop 40, but in case said cable is suddenly acted on by the rocker 30, or in the event said cable. should be drawn forward too far by said rocker, said spring yields for the protection of the reaches 20 and 22 and the equalizer' itself. In this last event the cable 26, through the medium of the sheavc 39, swings the arm 36 away from the stop 40, thus shortening;` the distance between the sheaves 35 and 45 by way of said first-named sheave.

As soon as the rocker 30 is returned to initial position, or is permitted to be so repower-controlling elements are left ready for use in the usual and customary manner.

The rocker 30 forms part of an oscillatory actuator for the cable 26, or for an electric switch hereinafter described. There is a second rocker 47, which is pivotally attached at 4S to the wall l, or to a face-plate 49, interposed between the inner face of said wall and said rocker, which .is also the case with the rocker 30, such plates appearing in Fig. 1. The rockers 30 and 47 are horizontally or approximately so, and pivotally .mounted intermediate of their ends. The other elements of the said actuator, besides the two rockers, consist of a chain or cable 50, which connects the front ends of said rockers, chains or cables 51 and 52 which respectively depend and rise from the rear ends of said rockers, and a rod 53 to the top and bottom ends of which the bottom terminal of said cable 51 and the upper terminal of said cable 52 are respectively at-V tuator cables are here connected. withV the rockers by means of pins 54. The pins 54 project. to the left from the rockers'at or adjacent to the ends thereof. 1t is now clear thatforce applied to this actuator at any point, as to the rod 53, or to the cable 50, in a manner to move said rod or cable in the direction of its length, is transmitted to the actuator as a whole and causes it to rock on the pivots 31 and 48, Such rocking movement does not throw the front and rear rocker connecting members out of parallel relationship, and the amount of saidY movement required for my purpose is so slight, comparatively, that the decrease in distance between said connecting` members, produced by said movement, is negligible. The actuatoris disposed in Fig. 6 1n its extreme opera-V tive position. When the actuator is caused to Vassume this position, the neutralizer is caused to shift the cable reaches 20 and :22 to neutral position, and by so doing to sto-p the elevator, in the construction which includes said equalizer.

Extending below the edge of the floor 4, which is directly in front of the elevator well, is a horizontal, yielding or flexible member, in the form of a chain, cable, cord, or the like, the same being represented at 55. This is the primary element of the landing guard. And extending below the front edge of the elevator platform 6 is a similar member, in similar form,rwhich is represented at 56. This second flexible member is the primary element of the elevator guard. A secondary element of the landing guard consists of a plurality of vertical chains, cords, or the like, the same being represented at 57, which have their lower ends fastened to the cord 55, and their upper ends fastened to the lower edge of a thin plate 58, which latter is secured to the vedge of the floor 4 above said cord.v And a secondary element of the elevator guard consists of a plurality I of vertical chains, cords, or the like, the

same being represented at 59, which have their lower ends fastened to the cord 56, and their upper ends fastened to the bottom edge of a thin plate 60, whichvlatter is secured to the front edge of the platform 6. A tertiary element of this elevator guard consists of a netting of chains, cords, or the like, or

an equivalent memberor members, the saine being'here represented, at 61, in the forni of a netting of cords-see Figs. 8 Vand 9. In these views theV cord netting 6l is attached at the front end to the cord 56, and at the back end to a row of pins 62 underneath the platform 6 adjacent to the back edge thereof.

Trip mechanisms, -presently to be described, are interposed between the cords 55 and 56 and the actuator which causes Ythe power to be shut oftI from the elevator.

Each of these mechanisms is tripped by a the Vnetting 6l, as the case may be. Any` object which extends beyond the front edge of the platform 6, when the latter is ascending to the floor 4, either encounters the cord 55 or the cords 57 and so tends to 4draw said Y scending, and acts on the cord 56 to draw it inwardly at the ends. It will presently Vape pear why the cords 55 and 56 are'drawn inwardly at the ends whenever they are subjected to strain at intermediate points. Owing to theV construction of theguards, of which the cords 55 and 56 are the primary elements, which construction has just been described, the aforesaid strain is effective, whether applied from below or from above, or from behind as when the netting 61 is the medium. And this would be true if the strain were applied from any other direction. Y

Before describing the trip mechanisms I desire to point out several additional structural parts and members. Y

Fastened to the inside of the wall 1 at the front edge is avertical bracket 63 which is provided on the front with ak cover 64. The

cord 55 inwardly at the end"s,;and any VVobr .j

so f

bracket 63 projects forward under the floor 4, and is located a short distance below said floor. A vertical bracket V65 is fastened to the wall 2,'on the inside at the front edge, and just below the level of the underside of the floor 4-see Figs. 1 and 4. A spindle 66 is journaled in the bracket 65, and a sheave 67 is mounted on said spindle. The ar rangement is such 'that the sheave 67 is at right-angles to the wall 2, and theV bottom of said sheave is in line with the horizontal portion ofthe cord 55. An angular, corner bracket 68 depends from the right-hand, front corner of the platform 6, and a similar bracket 69 depends from the left-hand, front corner of said platform. As sho-wn in Figs. 8, 10, and 11, a sheave 70 is mounted on a stud 71 which projects inwardly from the front of the bracket 69, such sheave being parallel with such front, and the bottom of said sheave being in line with the main horizontal portion ofthe cord 56. And a sheave 72 is mounted on a stud 73 which projects inwardly from the side of the bracket 69,

said sheave being at right-angles to the sheave 70 and at a higher elevation. An angular, horizontal bracket 74k is secured to the underside oit' the platform 6, at the righthand edge a short distance behind the bracket The bracket 74. is provided at the front end of its side, on the outside, with a vertical abutment 75, :from the upper and lower ends of which arms 76-76 extend rearwardly.

It may be observed here that the positions of the abutment 75 and the arms 76 are suoli that the actuator cable 50 passes through said arms, which are perforated, as represented at 77-77 in Figs. 22, 23, and 25, for that purpose, and directly back of said abutment. Under normal conditions the members 75 and 76 travel up and down with the elevator without interfering with the cable 50, and the latter is free to move up and down in the openings 77.

A bearing bracket 78 is -fastened against the inside face ot' the wall 1 back of the bracket 63. Mention may also be made, before taking up the landing and elevator trip mechanisms, which will be done in the order named, of a sheave 79 and a rack 80. The sheave 79 is mounted on a stud 81 which extends inwardly from the wall 2, as clearly shown in Fig. at. The sheave 79 is positioned at a higher elevation than the adjacent sheave 67, and at righteangles thereto. The rack 80 is secured to the front side of the right-hand elevator upright 7, and arranged with the teeth at the right and projecting in that direction beyond said upright. The fragments of this rack which appear in Figs. 12, 17, and 19, are rear elevations of the same, detached, but their position relative to the landing trip mechanism in each view is correct, and they are necessary in order to obtain a clear, complete, and comprehensive understanding ot' said mechanism. The rack 80 is very closely identified with the landing trip mechanism, and may be said to form a part thereof.

Referring more particularly to Figs. 12 to 20, inclusive, it will be seen that the landing trip mechanism comprises, besides the rack 80, a horizontal rock-shaft 82 journaled in the brackets 63 and 78 and having an upwardly-directed crank-arm 83 at the rear end, a spring-pressed operating arm 84 and latch 85 at the front end of said rock-shaft, a short, horizontal rod or swivel 86 carried at the upper end of said crank-arm, a slide 87 rigidly attached to the actuator rod 53, a vertical, fixed guide 88 for said slide, an arm 89 pivotally connected at the top with said slide and having an inwardly-extending tooth 90 at the bottom to engage the teeth of said rack, a rod 91 rigidly attached at the top to a forwardly-extend1ng lug 92 at the base of said arm, and operatively connetted with said swivel, and a fixed cam 93.

In `addition to these parts and members, there is a setting device comprising a block 91 loosely mounted on the rock-shaft 82, an upstanding lever 95 pivoted at 96 to Said block, `and a lug or pin 97 projecting from said rock-shaft into the path of a lug 98 at or adjacent to the base of said lever.

The arm 84 is rigidly attached to the front end of the rockshaft, in front of the bracket 63, and the greater length of said arm is at the left of said rock-shaft. The latch 8.5 has its base pivotally connected at 99 with the arm 84 at the left-hand end, and extends upwardly from said arm. A spring 100 is attached at the bottom to the arm 84 at a point beyond the rock-shaft 82 to the right, and at the top to the latch well up to ward a hook 101 which is formed in the right-hand edge of said latch near the top. A lug 102 projects from the frontl of the bracket 63, adjacent to the right-hand edge thereof, and is in the path of the hook 101 when the latch 85 is actuated upwardly, by the rock-shaft 82 and the arm 84, and rocked on its pivot 99 toward said lug, by the spring 100. The spring 100 has a constant tendency to cause the rock-shaft 82 to be rocked to the left, but is prevened from so doing while the hook 101 is in engagement with the lug 102. As soon, however, as the latch 85 is drawn away from the lug 102 and the hook 101 clears said lug, the spring 100 draws the arm 8a upwardly at the short end, and so rocks the rock-shaft 82 to the left-see Fig. 20. Normally the latch 85 is in engagement with the lug 102, and the connected parts are disposed accordingly, as shown in. Fig. 16.

The right-hand end of the cord 55 is attached to the latch 85 at an intermediate 1in point, and said cord passes directly across to and under the sheave 67, up and over the sheave 79, and down to a weight 103 which is suspended from said cord at this end. The weight 103 is heavy enough to permit 110 the cord 55, when strained, to spring the latch 85, while at the same time affording yieldingmeans whereby continued pressure on said cord, in the event the elevator continues to travel some distance after the 115 power is shut oli", simply causes the cord to draw up the weight without injury to the thing that is in contact with the cord. The cord 55 could be forced clear to the bottom edge of the plate 58, by the ascending ele- 120 vator and an interposed object, without seriously injuring such object, but before any such extreme displacement can occur the ele'- vator comes to a stop.

A collar 111 is secured to the cord 55 at a 125 point which enables it to bear against the right-hand edges of the front of the bracket and a bridge-piece 112, which latter is attached to said bracket front, and so to relieve from the weight 103 that portion of 130 collar 111 is sufficient for the proper action Y soYV of .the latch v85.

The' cover'64 is .cut out at 113 to receive a portion of and accommodate the spring 100, and the movement of said latch, when tripped, is limited by said spring and the contiguous edge of such opening, even when said cord is understress from the weight 103.V

A collar 104 and a set-screw-'105 are applied t0 the swivel 86 in front of the crankarm 83. The swivel 86 is free to rotate in the crank-arm 83, and is pierced transversely, behind said crank-arm 83, to receive' the rod v91, which latter works up and down through said swivel. The guide 88 is a rib atV the rear edgeof a bracket 106 which is fastened to the inner face of the wall l, in front of theright-hand elevator guide 7. Horizontal arms 107 '107 at the top and bottom of the bracket 106, serve as guides for the rod 53, such arms being perforated to accommodate saidrod'.vr The slide 87 has a vertical slot- 108, inthe side thereof which is adjacent to the l,verticalV portion of the bracket 106,' to receive the guide 88., and said slide operates between the arms 107. The slide 87 is secured to the rod 53 by means of al horizontal' pin V109, and the' same pin serves as the pivotvfor the arm 89, there being a vertical Yslot 110.in said slide to receive the upper terminal of said arm. The arm 89 extends downwardly from the slide 87 in 'front of the rod. 53, and the tooth90, at the base of said arm, projects rearwardly into position to be thrust into engagement with A the teeth of the `.rack 80.. .Vhen .the slide 87 is at the lowerend of its travel, the

rockers 30 and 47 are positioned horizon-Y tally' or approximately so, and, when. said slide is atthe upper end ofitstrayel, said` rockers are tiltedforward, as shown in Fig, 6. The arms 107 ,'therefore, limit the movement of the actuator.

The cam plate or stationary.` cam 93 de-l pends from an linWardly-exteiiding arm 114 at the top of aV plate 115'which is secured to the wall 1 below the bracket 106.V The rod'A 53v extends through and operatesin'the arm 114, the bottom being perforated, like the arms 107, for the accommodation of said rod. The cam 93 projects into thek path of',

the tooth 90.'

The block 94 is held againstendwisemove-i ment, on the rock-shaft 82, bymeans ofthe pin-97 which is at Vthe front end ofsaid block, and a pin 116 which projects from said rock-shaft at therear end offsaidv block.v

The lever 95 is pivotedto. the block 94 between the latter and the wall 1, and the. lug

98 projects forwardly overthefpin 97. The.

latterV has an upward inf'zli'nationY at all times.

Normally the lever, 95 'stands' approximately. upright.` A supportingguide'1174isipro-V tened again-st the inside face of the wall 1.

The mechanism illustrated in Figs. 12 and 13, also the setting device shown in Figs. 14 and 15, are in normal or initial position,

The trip mechanism just described operates in the following manner :v When the latch is tripped by the cord 55, the spring 100 causes 'the' rock-shaft 82 with its crankarm 83 to rock to the left, and the arm 89 is swung o-n its pivot 109 by said crank-arm in the same direction, through the medium of .the swivel 86 and the rod 91, until the' tooth engages the rack 80, as shown in Figs.V 17 and 18. Assuming that the elevator be rising at this time, the rack 80, acting through the tooth 90,the arm 89, the slide 87, and the pin 109, forces the rod 53 upwardly, and

by this means and in this manner the actu-V mechanism, simply grasp the lever and force it forward on its'pivot 96. This action causes the pin 97 to be forced downwardly by the lug 98. The pin 97 carries with it the rock-shaft 82, rocking thesame to :the right. The partial rotation to the right of the rock-shaft 82 causes the tooth 90 to be withdrawn from engagement with the rack 80, and causes the latch 85 to be rengaged with the lug 102. The slide 87 and the'rod 53 are free to descend now, when the actuator is restored to initial or normal position, and the mechanism is ready Yto be tripped again by the cord 55.

In the event the upward travel of the elevator be considerable, after the power is shutoff by the action of the landing trip mechanism, the tooth 90 is carried into engagement with the cam 93, and by said cam forced out of engagement with the rack 80, as shown in Fig. 19. This occurs before the block 87 reaches the-upper'arm107, and prevents breaking or straining any of the parts. Nhen the tooth 90 is Vforced to the right bythe cam 93, itbrings about the automatic resetting .of the trip mechanism,

of whichsaid toothforms a part, inasmuch' as the arm 89 isv swung in the same direction, and carries with it the rod 91, swivel 86, crank-arm 83, and rock-shaft 82, and the latter causes the latch 85 to be rengaged with the lug 102. The rod- 53 can now descend, as when the resetting is done with the lever 95. Unless the obstacle which causes the trippingof the trip mechanism be removed, said mechanism can remain set only so long as the tooth 90 is in engagement with the cam 93, as will be readily seen, so that the resetting, in order to be effective, must as a rule be done by hand and after removing the tripping obstacle.

It is to be remembered, in considering the explanation of the operation of this trip mechanism, that the parts appearing in Figs. 12, 17, and .19 are viewed from behind;

Referring next to Figs. 21 to 25, inclusive, more especially, for the elevator trip mechanism, it will be observed that such mechanism comprises an upwardly spring-pressed, vertical plunger 118, a spring-pressed latch 119 for said plunger, an oscillatory wedgeblock 120 which coperates with the abutment 75, the latter really constituting a part of this trip mechanism, and an arm 121. The abutment 75 and the wedge-block 120 form a clutch for the actuator cable 50.

The plunger 118 is arranged to slide in two perforated lugs or arms 122 which extend from the side of the bracket 68 parallel with the front of said bracket. A horizontal pin 123 extends through the plunger 118 below the arm 122, and projects into and operates in a vertical slot 124: in the front of the bracket 68. The pin 123, by reason of its extension into the slot 124, assists in preventing the plunger 118 from turning on its axis. A spring 125 encirc-les the plunger 118 between the lower arm 122 and the pin 123. The upper terminal of the plunger 118 has a slot 126 therein, which extends through from front to back, and a. pin 127 is inserted in said plunger and arranged across said slot at the upper end.

The latch 119 is pivoted at the lower end, at 128, to the back side of the front of the bracket G8, and said latch has a hook 129 at the upper terminal to engage the pin 124. The latch 119 may have a lug 130 at the base provided with a. rearwardly-eXtending pin 131, which pin is adapted to be engaged by the spring 125, for the purpose of yieldingly retaining said latch or its hook 129 in contact with the pin 123, but I prefer to rely mainly for such contact upon a spring 132. The spring 132 is attached to two pins 133 set in the front of the bracket 68 and projecting back of such front, and said spring is arranged to bear on the latch 119 in such a way as to urge the hook 129 into contact with the pin 123. The latch 119 is urged by the springs 125 and 132 toward the right, it being remembered that the parts which appear in Figs. 21 and 21 are viewed from behind.

In Fig. 22, a lip 134 on the side of the bracket 68, between the arms 122, is broken Off to disclose the latch 119, the right-hand edge of which is shown, and the front of said bracket is cut away to show the slot 124.

vWhen the plunger 11S is forced downwardly, against the resiliency of thc spring 125, the latch hook 129 passes over the contiguous terminal of the pin 123 and holds said plunger in depressed position. And when the latch 1.19 is rocked to the right, against the resiliency of the springs 125 and 132, the hook 129 slips ott' of the pin 123 and releases the plunger 11S to said spring 125, which immediately forces said plunger upwardly. rlhe normal positions of the parts are shown in Figs. 21 and The cord 56 has its right-hand end attached to the latch 119, and a pull on said cord trips said latch and releases the plunger 118, as shown in Figs. 24 and 25. The cord 5G extends straightaway from the latch 119 across to and part way around the sheave 70, up to and over the sheave 72, and rearwardly to a tension member, which here is a spring 135-see Figs. 8, 10, and 11. The rear end of the spring 135 is fastened at 13G, Fig. 8, to the underside of the platform G, and the other end of said spring is attached to the cord 5G. The spring 135 performs a similar function for the cord 56 that the weightr103 performs for the cord 55; and said cord 56 is provided with a collar 137, which is similar to and for a similar purpose as the collar 111. The collar 137 bears against the right-hand edges of the bracket G9 and a bridge-piece 138 which is secured to the back side of the front of said bracket.

The wedge-block 120 is pivotally att-ached near the rear end, at 139, to the depending side of the bracket 711. There is a longitudinal slot 140 in the wedge-block 120, through which at the rear end the pivot 139 passes into the aforesaid side of the bracket 71, and a spring` 141 is located in said slot between said pivot, which such spring bears against, and the front end of said slot. A lug 141-2 projects from the bracket side into a notch 143 in the upper edge of the wedge block 120, adjacent to thel rear end thereof, and the back wall of such notch forms a lug 1114 which contacts with and bears against said first-named lug. rlhe notch 113 is larger than the lug 142, being suliciently ylarge to permit all necessary play on the part of the wedge-block 120. The front end or nose of the wedge-block is in quite close proximity to the abutment 75, and the actuator cable 50 is received between such nose and abutment. A setting lever 115 rises from the wedge-block into position to be grasped by the operator on the elevator platform, and it may be observed here, also, that the settmg lever 95 is in position usually to be grasped by said Operator, when the elevator is stopped by reason of the displacement or the diverting of the cord In some rare cases the elevator might be stopped in a position where the operator on the plaform 6 could not reach the lever 95, and in such cases this leverwould have to be reached from some other point.

- The rear terminal of the arm 121 is secured to the inside face of the wedge-block 120, as represented at' 146, in Figs..V 22, 23, and 25. The arm` 121, after leaving the wedge-block, extends forward and has its front end introduced into the plunger slot 126. The side of the 1bracket'74 is cut out at 147`7toV accommodate the rear end portion of the arm 121, and the latter is o'set at 148, Fig. 23, to enable it to clear the front end portion of. said bracket side.

Vhen the plunger 118 is released from the latch .119, vand rises under the impulse of the spring-125, the front end of the arm 121 is carried up with lsaid plunger, and said arm in turn rocks the wedge-block 1.20 on the pivot 139, and causes it to grip with its nose the cable 50 between such nose and the abutment 75, said cable being forced by said nose tightly against said abutment-see Figs. 24 and 25. The cable 50 is thus carried down with the descending elevator, and the actuator operated to shut oif the power.

While the cable 50- is in the grasp of the wedge-block and the abutment 75, the actuator can not be thrown or drawn back to normal position, consequently the elevator can not be started until this trip mechanism is reset. The said mechanism is set or reset simply by forcing the lever forward. This action rocks the wedge-block 120, on the pivot 139 and the lug 144 on the lug 142,V

`downwardly, releases the cables 50, and,v

through the medium of the arm 121forceS the plunger 118 down until the latch hook 129 slips over the pin 123. The mechanism is now normally disposed, as illustrated in Figs. 21 and 22. The mechanismis now ready for a repetition of the tripping action and stopping operation.

The movement of the latch 119, when tripped by the cord 56, is limited by the upper arm 122, with whichl the Vtop of said latch or of the hook 129'then comes into contact, but not until said hook has released the pin 123.

The upward movement 0f the wedge-block 120, with the attached and associated parts, is limited and may be varied by a screw 149l tapped into and Vthrough the upper arm 76. The wedge-block strikes the bottomof the screw 149 when 'said wedge-block is forced upward; By turning the screw 149 up orV down the movement of the'wedge-block is increased or decreased accordingly.

In'the event the elevator continues to de scend, after the power is shut off, to an extent that Vwould ordinarily threaten injuryV to the actuator, the cord 50 of which is in the grasp of the wedge-block 120 and abutment 75, the spring 141 becomes an important factor, since it affords the needed relief and said wedge-block and abutment slide down on said cable without breaking, un-V duly straining, or otherwise injuring either the cable lor other parts of the actuator. The spring 141 normally forces the wedge-block forward as far as the pivot 139 and the rear switch such as is shown in Fig. 26 is used to f open and .close the electric. circuit.

This view-is a side elevation.. The switch herein shown consists yofV a fixed contact member 150, an oscillatory contactmember 151 pivotally attached at 152 to an arm 153, of inirst-named member, and a spring 154 arranged to force said member into contact with said member 150, and so Vto close the circuit. Wires 155 and 156 areattached, re-

a sulating material, which projects fromsaid spectively to the contact members 150 and 151. An actuator rocker 157, generally similar to the rocker 30, is shown. This rocker has pivoted thereto at 163an arm 158.l lThe arm 158 Aextends forwardly toward the contact member 151, on a. plane which is below the pivot 152, and a plunger 159, of insulating material, extends' from said arm into: contact with said member. The arm 158, forward of the pivotally-attached, rear terminal, is tubular, and. the rear terminal portion-of the plunger 159 fits and slides within the tubular part` of said.

arm. A spring 160 is introduced into the arm 158, between the endof the passage therein and the inner` end Voit' the plunger 159, to afford a yielding contact between said plunger and the member 151, and absorb any undue shock that may be experienced bythe parts when they are operated. A support 161 having a swivel, supporting guide 162 for the plunger 159 is provided to maintain the arm 158 and said plunger in the position mentioned above. series of holes 164 is provided, in therocker 157, to permit the pivot 163v to be adjusted 'for the purpose of varying the stroke of the arm 158 and plunger159, when said rocker is tilted forward. Cables 50 and 51, for which there are'two pins 54, are employed in this as in then other case. Obviously the spring 160 when expanded should be somewhat stronger than the spring 154.

Iand separates said first-named contact member from said second-named"contact member, thus breaking the circuit and shutting offvthe'power; fromthe elevatori Upon the release of the actuator', of whichthe rocker 157 is apa-rt; from the trip mechanism that caused the same to operate, the springs 154 and 1GO actE to force back the plunger 159 and arm 158 and to restore said rocker with said actuator to initial position, and said spring 154 at the'same time rocks the member 151 into contact with themember 150, and closes the circuit through the switch.`

The general operation'oflthis appliance as a wholewill be quite wellfunderstood from tlieforegoing description and explanation, hence the'same need be but briefly outlined further'.

Assuming that the cablereaches 2O and 22 and the cable branchesf28 and- 29 are disposed asin Fig. 2, when the elevator is ascending, and that thel platform 6 is approaching the floor 4, and assuming, furthermore, that the cord55is deflected, either by force applied to'some one or more of the cords 57 or directly to said cord 55 itself, the latter exerts a pull onfthe latch 85 and trips the same, when the spring 100 causes the rock-shaft 82 to be partiallyrotated,

.and iny turn to cause theA tooth 90' to be thrown into engagement with the'ascending rack 80. The rack 80 carries up the tooth 90, arm 89, and slide 87, and with the latter the rod 53. The rod 53, being attached to the actuator cables '51' and 52, carries said cables upwardt with it, thereby rocking the rockers 30 and 47 forward on their pivots 31 and 48,

respectively', and causing the cable 50l to move down. The rocker 30, in the forward movement justimparted to it, takes with it the connected portion of the cable 26 and so draws on said cable and causes the same to draw `up the branch 29 and shift thereaches 22 and 20, until the parts are neutrally` disposed, as in Fig. 4. The shifting `of the reaches 20 andv 22ll shuts off the power from the elevator. It hasV beenv explained how the same result is attained with the rocker 157.

Meanwhile the weight 10S-yields tofrelieve the cord 5.)1 to whatever extent may be necessary", by permitting ay sufficient amount of said cord to be drawn to theright, from beneath the sheave 67, to make up or' provide for any excessive deflection of said cord.

Alfter the elevator comes to a stop, the lever 95l is thrown. forward to reset the trip mechanism, unlessl said elevator had continued far enough, after the power was disconnected, s'o rthat thev cam 93 has caused said mechanism to be reset, and it remained reset.- In either event, the toothl 90`is thrown out of engagement with the rack 80, andthe actuator is left free.` The'ractuator being free,y the cable reaches20 and 22 can' be ma- 1 r6.6 .fr'ri'pulatedl tc start: the elevator :in.:eit'her fdi-V rection'.y When either of the said reaches next-moves or is moved downward, it'carries with it the `attached braneht28-or 29), and, through the medium of such branch, draws on the cable 26,l and causes the latter to rock* backv the actuator and leave the same in readiness for subsequent active operation. The springs 154and160 perform a similar service for the actuator in the other example.

Assuming that the cablereaches20 and 75 especially when the elevator is approaiing' more nearly to the bottom of the well), said cord 5G exerts a pull onthe latch 119 and causes said latch to release the plunger 118 to the spring 125, when saidY Spring forces saidV plunger upwardly, and thereby causes the arm 121 and the wedge-'block 120 to be rocked'in the same direction. In its upward movement the wedge-bloclr120 grips the cable 50. The cable `50 is carried down with rile descending elevator, and the actuator rocked to shut offy the power, by means of either the neutralizer or the electric switch, the action of each being the-sameas when said actuator is operated through the medium of the landing trip mechanism. In theca'se of the shift cable, the positionsof the parts change fromthose shown in Fig; 3aga1n to those shown in Fig. 4.

Meanwhile the spring 135 yieldsto relieve the cord 56 to whatever extent may be necessary, by permitting a sufficient amount of said cord to be drawn tothe right, from beneath the sheave 70, to take up or provide for any excessive deflection of said cord.

After the elevator comes to a stop, the lever 145 is thrown forward to reset the trip mechanism. In the resetting operation the cable 50 is released from the grip of the wedge-block 120. The actuator is now free, and it is restored to initialposition by either of the agencies and ineither manner already very fully described and set forth.

The spring 141 enables the elevator to continue its descent, afterthe power has been ,u

shut offby the action or through the medium `of the actuator, without trip ing the cable ible member adapted when deflected to exert and said means.

4adjacent to the lower,

arm, in which event, or in case the active movement of said elevator be stopped by some other means, 'as by the neutralizer when movement thereof is exhausted by said actuator, said clutch slips on said cable, unless or until said elevator comes to a stop. When the actuator is returned to normal position,

the slide 87 is carried down to the -starting point, which is on or in close proximity to the lower arm 107,

The actuator may be counterweighted to counteibalance the rod 53 and attached parts, whichv are provided for each licor, and as a rule should be counterweighted in order to lessen the force required to rock said actuator to stop the elevator. In Figs. 1 and 5 I show one means of applying a counterbalance to the actuator, such means consisting of a weight 166 suspended by a cord 165 from a pin 54 which projects from the rocker 47 front corner thereof. 'Ihis weight counterbalances the rod 53 and attached parts and so relieves the actuator from the weight of said rod and parts as a restraining factor when said actuator is operated by either trip mechanism.
